摘要
本文从马角坝剖面石炭系海相碳酸盐岩和腕足化石的锶同位素变化出发,讨论了锶同位素地层曲线的地质意义,并且指出海相碳酸盐岩和腕足化石的锶同位素组成可作为了解地球构造演化的工具。
Based on the strontium isotope variations of the Carboniferous marine carbonates and brachiopod shells from Majiaoba profile the paper discusses the implication of strontium isotopic stratigraphic curve and suggests that the strontium isotopic compositions of marine carbonates and brachiopod shells may provide a tool for understanding the tectionic evolution of the Earth.
